Saving power and energy is always helpful not just to cut down on your power bills but it also helps you in reducing global warming and helps you conserve the energy and keep our planet earth green and clean. In order to ensure that our products help its users to save energy, reduce electricity bills and conserve greenery on earth we pass them through several tests. These tests are performed to ensure the quality, power they consume and power they save.
Energy saver lights conducted a test in a laboratory accredited by the national voluntary laboratory accreditation program to test the minimum efficacy of compact fluorescent lamp bulbs (this test description is applicable to the Dimmable 3-way CFLs)
The test was conducted by taking 10 units of light bulbs. The bulbs were tested under different conditions that were created by the manufacturer specifically.
The energy star requirements of the bulb were tested by choosing the following lumens:
Bare lamp
(Dimmable/2-way/3-way):
Lamp power < 15 50
Lamp power = 15 60
The light bulbs were first tested correlated color temperature. The requirement of this test was 10 units per model – 5 base-up/5 base-down unless the manufacturer restricts specific use or position. If position restricted, manufacturer must test all 10 samples in restricted position. For dimmable/2- dimmable/2- way/3-way products, measurements must be made at the highest wattage setting listed for the model.
In this test Partner must identify one of the following designated correlated color temperatures and use the designated descriptor to market their product as: 2700K (warm white), 3000K (soft white), 3500K (white), 4100K (cool white), 5000K (natural), or 6500K (daylight), and at least 9 out of the 10 samples tested must fall within a 7-step ANSI MacAdam ellipse for that color temperature at the 100 hour lumen measurement. Please refer to Section 11 for CCT quality assurance requirements and Appendix C/ANSI Color Ellipses.
The bulbs were then tested for their color rending index in which again Average of the 10 samples tested must be greater than 80, and no more than 2 individual samples can have a CRI less than 77. In this color rending index test of the bulbs Partner must identify one of the following designated correlated color temperatures and use the designated descriptor to market their product as: 2700K (warm white), 3000K (soft white), 3500K (white), 4100K (cool white), 5000K (natural), or 6500K (daylight), and at least 9 out of the 10 samples tested must fall within a 7-step ANSI MacAdam ellipse for that color temperature at the 100 hour lumen measurement. Please refer to Section 11 for CCT quality assurance requirements and Appendix C/ANSI Color Ellipses.
